first off all of the reviews saying it is terrible all sound like simple controller/keyboard/console/pc malfunctions I saw someone write about this saying that the running and walking delay which i have not experienced with a relatively new controller and an xbox one from 2016, yes the game is less realistic than modern warfare but personally I like that anyway i think this game is great if your system is up to date and you have an internet connection i would recommend this game 5/5
Edit: i am seeing people saying it is too hard to exfil in zombies so theyre giving a bad rating, honestly just dont exfil you will play longer and have more fun
